Which units (based on their appearance) in the Elven Castle do you dislike?

I don't like Ents in any of the games for some reason. They don't seem like anything special, but they just aren't appealing to me as creatures. I don't like them. By the way, dragons were definitely better in the third game; the ones here aren't particularly impressive in their base form, but the upgraded ones are simply gorgeous, in my opinion.
